Use uppercase for the first character in the element and lowercase for the second character. My idea was to write out the LHS and let the OP work out the RHS, but once i realised youd have to cancel down the H+ and H2O i decided it would make life too complicated and possibly cause confusion, so i just removed that bit anyways. Damn i just noticed the first equation was written out wrong by me shengoc. Balancing Strategies: In this combination reaction we have S and O2 combining to form SO2. Combine so as that electrons cancel. Electrons go on … ClO4- --> Cl- (reduction) SO3(2-) --> SO4(2-) (oxidation) Balance the reduction half-reaction.
